Linear Velocity Formula:
From: | To: |
Definition: This calculator converts between angular velocity (rotational speed) and linear velocity (straight-line speed) using the radius of rotation.
Purpose: It helps engineers, physicists, and technicians understand the relationship between rotational and linear motion in systems like wheels, gears, and turbines.
The calculator uses the formula:
Where:
Explanation: The linear speed at any point on a rotating object equals the angular speed multiplied by the distance from the rotation axis.
Details: Understanding this relationship is crucial for designing mechanical systems, calculating belt speeds, determining gear ratios, and analyzing rotational dynamics.
Tips: Enter the angular velocity in radians per second and the radius in meters. Both values must be positive numbers.
Q1: How do I convert RPM to rad/s?
A: Multiply RPM by 2π/60 (1 RPM = 0.10472 rad/s).
Q2: Does this work for any rotating object?
A: Yes, as long as you use the correct radius from the axis of rotation to the point of interest.
Q3: What if I know linear velocity and need angular velocity?
A: Rearrange the formula: ω = V/r.
Q4: Why is radius important in this calculation?
A: Points farther from the axis move faster than points closer to the axis at the same angular velocity.
Q5: Can I use different units?
A: Yes, but all units must be consistent (e.g., if radius is in cm, velocity will be in cm/s).
